" </td>\n"; print "<td>"; // If the field is an empty array, parse it if (is_array($value)) { foreach ($value as $selkey => $selvalue) { print $selkey . " : ". $selvalue ." <br />";} } else { // Else (not array) just print the value // in second column print $value .

If you get it OK from there something's going wrong between your form and the handler page. Have you definitely set the action to the correct handler?

darrenfinch Posted March 10, 2006 Author Share Posted March 10, 2006 I thought with PHP 5 you were supposed to use the superglobal variables ?I found with other forms I have had to use $_POST in all cases (POST returns blanks)i.e. POST becomes $_POSTI tried it without the $_ and I still get the sameand if I use the same method ($_POST) with the phpinfo () I see the variables, so I assume that the form input is correct but somehow the variables are not being passed/parsed correctly in the handler1.php script but I cannot see why!I dont think it is the web server either (everything else I have thrown at it works great) [!--quoteo(post=353576:date=Mar 10 2006, 05:26 AM:name=lessthanthree)--][div class=\'quotetop\']QUOTE(lessthanthree @ Mar 10 2006, 05:26 AM) [snapback]353576[/snapback][/div][div class=\'quotemain\'][!--quotec--][code]<?php//Generic form data parser// Begin HTML page and field tableecho "<html><head><title>Check Form</title></head><body><table cellpadding=20 border=1>";echo "<tr><td><b>Name</b></td><td><b>Value</b></td></tr>";// For each $_POST valueforeach ($_POST as $key => $value){ // Print the key in the first column print "<tr><td>" . $key .

lessthanthree Posted March 10, 2006 Share Posted March 10, 2006 The form method should still be set to POST if that's what you mean.I think i might have misunderstood your post though.

AndyB Posted March 10, 2006 Share Posted March 10, 2006 Two questions:#1 - are you actually saving your work as a .php file rather than as a .html file?#2 - are you testing this on a live server or just in some editor preview mode?
